The Penn Medicine Orphan Disease Center (ODC) will host the 5th Annual Million Dollar Bike Ride on Sunday, May 20, to raise money for rare disease research. The Million Dollar Bike Ride (MDBR) brings over 500 cyclists and volunteers to Penn’s campus to ride either 13, 34, or 72 miles starting in the city, and ranging across the Greater Philadelphia region. In four years, the MDBR’s 25+ teams have raised over $6.4 million to fund research grants on the diseases they represent. The ODC ensures that 100 percent of the funds raised goes towards these pilot grants, with no overhead taken out. Please join the ODC in cycling on a beautiful spring day in the name of rare disease research! Details and registration can be found at www.milliondollarbikeride.org.
